IMPROVEMENT IN GANG-FLOWS.

Specification forming part of Letters Patent No. 48,6279, dated July 11,1865.

To all whom t may concern Be it known that I, A. HAMMOND, of Jacksonville, in the county of Morgan and State of Illinois, have invented anew and Improved Gang and Trench Plow; and I do hereby de- Clare thatthe following is afull, clear, and exact description thereof, which willenable those skilled in the art to make and use the same, referencebeing had to the accom panyin gdrawings, forming part of thisspecitcatiom in which- Figure 1 is aside view of my invention, the armof the wheel nearest the eye beingin section, as indicated by the line.fr Fig. 2; Fig. 2, a plan or top view of the same; Fig. 3, a'transverse vertical section ofthe same, taken Vin the line w Fig. 2.

Similar letters of reference indicate corresponding parts.

This invention relates to anew andimproved gang or trench plow 5 and itconsists in a novel construction and arrangement of parts, ashereinafter set i'orth, whereby the plows may be readily adjusted higheror lower, as may be desired, and also readily raised tomporairily outofthe ground when necessary-as, for instance, in turning at the end of afurrow or field.

A A represent two parallel beams, which j are rmly secured to an axle,B, havinga wheel,

f end, to catch into a rack, F, on D and hold it in position. l

G is the drivers seat, the supports of which are attached to the beams AA; and H are plows, which are secured to the beams in any proper'manner.

The arms e ofthe wheels C are attached to slides I, which have racks fat their back or rear edges. These slides I are tit-ted in sockets J,which are secured on the ends of the axle, the slides being. allowed toslide freely up and down in the sockets. Each slide I has a screw, K,gearing into it, and these screws are provided with cranks L at theirupper end for the purpose of turning them, the axes of the screws havingtheir bearings attached to the sockets J.

It will be seen from the above description that the beams, andconsequently the plows, may be raised andr lowered by turning the screwsK, and the plows regulated or adjusted so as tp plow furrows of auniform or equal depth, and the plows may be very quickly adjusted, avery few turns of the screws being sufficient for the purpose, and itmaybe done while the plow is in motion or at work.

flo the plank or timber D there is attached a segment-rack, L,into whicha pawl,M, catches, the latter being fitted in an upright, N, attached toone of the beams A. The pawlMis connected by a link, g, with afoot-lever, O, 4which has a spring, h, bearing against its under side,the spring having a tendency to keep the pawl M in contact with the rackL, as will be fully understood by referring to Fig. 3. By thisarrangement the "driver at any time, by stepping on the rear of theplank or timber D, will cause the rear of the beams A A to be tilted upand the plows to be raised out of the ground, the pawl M and rack Lpreventing the beams and plows from descending. The plows may be letdown at any time by depressing the lever O with the foot.

More or less land may be given the plows by adjusting the draft-pole E,as will be fully understood by referring to Fig. 2.

On the plank orl timber D there is abutton, P, which, when tn rned bythe foot so as to Vproject over one ofthe beams A, will prevent theplows from being tilted up or raised out of the ground, and admit of thedriver stand- .ing on said plank or timber in case he prefers I standingto sitting. l

The plows may be arranged so as to subsoil, trench, 'or turn regularfurrows for tillage. In moving the machine from place to place the plowsare elevated above the surface of the ground through the medium of thescrews, the

tilting ofthe beams being adopted only for temporary elevations, as inturning at the ends of the furrows, 85e.

I claim as new and desire to Secure by Let-- ters Patent- 1. Thesegment-rack L, pawl M, und footlever O, all arranged and applied to theplank or timber l) and beam A, substantially as l(tud for the purposespecified.

2. The button P, when applied to the plank or timber D and used .inconnection with the rack L, pwl M, and foot-lever O, for the purpose setforih.
